ZVT (Zavody automatizace a vypocetni techniky) PP-01

The ZVT SMEP PP-01 is an 8-bit microcomputer developed in the 1980s in Slovakia by the Research Institute of Computer Science (VÚVT).

The technical specs are as follow:
- 8080 microprocessor
- 64K RAM and 16K ROM
- 256x256 pixels display in 8 colors

Uses 3 bit-planes for graphics.


According to Jan Ciger there was also PP-03 (same as PP-01, but with
color support) and PP-06 (basicaly an IBM PC clone, with 4MHz 8086 CPU)

Hynek Med added that "the PP-06 was a PC-XT clone with two 360k floppies
(sometimes 20 MB MFM disk). I uses VUVT-DOS (a translation of MS-DOS),
and an expantions bus which wasn't compatible with ISA."


The PP 01 keyboard is located on a separate SM 2257 board. In addition
to the keyboard circuits, it also contains the interrupt request LED and
RUN LED, sound output (acoustic transducer - speaker) and circuits for
the INT0 and INT3 interrupt buttons.
